SPECIFICATION forming part of Letters Patent N 0. 456,485, dated July 21, 1891.

Application filed April 3, 1891- To aZZ whom it may concern: 4

Be it, known that I, GEORGE XV. GLAZIER, a citizen of the United States, and a resident of Salem, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Paper-BoX-Setting- Up Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in paper-boX'setting-np machines, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents atop plan of the 1111- proved machine. Fig. 2 represents a front elevation of the same. Fig. 3 represents a vertical section on the line X X, shown in Fig. 1. Fig. 4 represents a detail vertical section of the end blank feeding, pasting, and settingup mechanism. Fig. 5 representsa cross-section on the line Y Y, shown in Fig. 4. Fig. 6 represents a detail top plan of the box-support; and Fig. 7 represents a cross-section on the line Z Z, shown in Fig. 6. Fig. 8 represents a detail top plan of the end blank-feeder plate. Fig. 9 represents a bottom plan of the same. Fig. 10 represents a section on the line WV WV, shown in Figs. 8 and 9; and Fig. 11 represents a perspective view of the pasteboard box that is being put together by the improved machine.

Similar letters refer to similar parts where ever they occur on the different parts of the drawings.

In the drawings, A A is the frame of the machine, in hearings in which isjournaled the driving-shaft B, which is set in a rotary motion by means of belt-power applied to the pulley B, which is loose on the shaft, and caused to be brought against afriction-clutch B", secured to said shaft, when the machine is to be set in motion. The shaftB is started by the depression of a treadle B, pivoted to the frame A at a, and carries at its rear end a conical disk 13*, which comes in contact with and moves the pulley B in fricwhen the treadle B is depressed, thus causing the shaft B to rotate until said treadle is released and returned to its normal position Serial No. 387,532. (No model.)

0 on the crank-shaft C, which is journaled in hearings in the frame A A, as shown in Figs. 1 and 2.

G is a link, the rear end of which is journaled to the crank-shaft C, and having its forward end pivoted to the upper end of a lever D, which is pivoted in its lower end to a vertically-movable cross-bar D, to which the upwardly-projecting rods or posts D" D are secured, said rods being guided in suitable bearings on the frame A A, as shown in Figs. 1, 2, and 3. To the upper end of the link D is pivoted a similar link D having itsupper end pivoted to any stationary part of the machine, preferably to a plate or crossbar A, secured to the uprights or frame A A. E is the head, adjustably secured to the u pper ends of the rods D D, as shown. By

this arrangement a reciprocating movement is imparted to said head from the crank-shaft To the stationary plate A is securedthes;

post F, on the top of wh ich is secured and rests a the box-supporting block, which is preferably composed of a base-block G, resting on top of the post F. 011 the block Gare arranged.

the laterally-adjustable box-supports G G, I

preferably secured to the base G by means of screws g g going through slots G G in the box-supports G G. The parts G-G are preferably guided on the block G by means of pins or pins and rolls g g on the block G going through parallel slots G G in the adjustable supportsG as shown in detail in Figs. 6 and 7. The parts G G are adj ustable according to the width of the box that is to be set up in the machine.

g g are yielding springs secured to the sides of the box-supports G G for the purpose of holding the box in position on said supports while attaching the end pieces to it.

The machine for feeding and pasting the end pieces is constructed as follows:

To the n )er ends of the frames A A is secured a hollow frame H, having at its front portion a lateral dovetailed guide H, 011 which the angular plates or blank-guides I I are laterally adjustable to and from each other, accordingto the width of the box ends that are to be loaded between said angular plates, said plates being preferably adjustable by means of a right and left handed screw 1, working in nuts on dovetailed ears I" I, that form parts of the angular plates I I, said ears being capable of adjustment on the dovetailed guide H, for the purpose stated. The said adjusting-screw I is connected to a forked bracket I on the bar H, so as to be prevented from longitudinal movement, although free to be turned around its axis while adjusting the positions of the blankguides I I. To the hollow frame H are secured grooved guides h h, the forward ends of whichserve as supports for the end blanks.

K K, that are to be successively pasted, fed to, and stuck on the turned-over edges 71 k of the box-body K, as shown in Figs. 4 and 11.

L. is the back wall for the blanks K K, which is 'adjustably secured to the guides h h in a suitable manner, so as to change, its position relative to the front edges of the plates I I, according to the depth of the blank K that is being used.

M is the blank picker or feeder, by means of which one blank K at a time (the undermost in the pile in Fig. 4) is taken from the pile contained, between the walls I I and I and carried to the boX while held on the boxsupport, as shown in Fig. 4. Said feeder or picker has at its forward end an upwardlyprojecting, lip m,,adapted to come in contact with the rear edge of the bottom sheet K in the pile, Fig. 4, and thereby carry it, one at a time, to the box-support.

m m are spring wires or bars on the under side of the picker M, which springs project beyond the forward edge of said picker and serve as yielding supports on which the blank is carried to the place where it is to be stuck 011 the box-body. Said wires, being elastic, will permit the blank to be depressed upon saidboX-body by the action of the head E.

The picker M is reciprocated by mechanism from the crank-shaft O, as follows: On the shaft B, or other suitable part of the machine, is pivoted the lever N, which is actuated in one direction by means of a cam O" on the crank-shaft O acting on a pin or pin and roll 'n on said lever N, as shown in Figs. 1, 2, and 3. A spring N moves the lever N in an opposite direction. To the upper end of the lever N is adjustably connected a rod m", the forward end of which is pivoted or otherwise connected to the picker M.

The pasting device for automatically applying paste or adhesive substance to the under side of the lowest blank K in the pile is constructed as follows: On each of the side plates I I are pivoted a pair of parallel links OO,one of which has an eXtensionO', through which passes loosely a transverse rod 0, to

which is hinged the inner end of a rod 0 the outer end of which passes loosely through an car on the lever N and is provided in its outer end with adjusting-nuts 0 as shown in Figs. 1 and 3. To the lower ends of each set of the parallel links 0 O is pivoted a rack or spotter-bar 0 having teeth or projections on its upper side, as shown in Figs. 1, 3, 4, and 5. P is a receptacle containing paste or suitable adhesive liquid, into which the racks or spotter-bars O O dip intermittently and transfer the paste in spots on the under side of the blank at or near its side edges. The said spotter-bars are operated in one direction by the lever N and in the opposite direction by means of a spring 0 interposed between the rod 0" and a bracket'II" on the plate H. The dip of said spotter-bars O is regulated by means of an adjustable collar 0 on the rod 0 coming in contact with the bracket 11 during the forward motion of the lever- N, as shown in Figs. 1, 3, and 4. For the purpose of applying paste in spots to the under side of the blank at or near its forward edge I pivot at r a transverse rack or spotter-bar R, having slots R R, adapted to receive projections or extensions 0 on the side racks O 0 by which an upand-down rocking movement is automatically imparted to the said lateral rocker or spotter-bar 0 during the forwardand-back swinging motion of the side racks O 0 On the rear side of the stationary barI-I' is arranged a vertically-adjustable gate S, which is adjusted up, and down by means of asuitable regulating-screw S. (Shown in detail in Fig. 4.) In using the machine the gate S. is adjusted so that its lower edge is held in po sition above the bars h h, (on which the pile of blanks K rest,) so as to permit one blank at a time to be taken from the bottom of the pile and pushed forward by the feed-bar M. In practice I prefer to provide the gate S at its lower end with a forwardly-projecting foot-piece S adapted to hold the blank against the lipm on the feed-bar M after said lip has passed by the gate S, and thus preventing the blank from springing or moving upward away from said lip. I also prefer to use a pair of forwardly-projecting stationary bars S S secured to the stationary cross-bar H or frame H or other stationary part of the machine, for the purpose of holding the blank against the lip on on the feed-bar M while being fed onto the box-support, as shown in Figs. 3 and 4. If so desired, the said bars, S S may be dispensed with and the foot S-extended forward sufficiently to serve the purpose of and act as a substitute for said bars S S without departing from the spirit of my invention. The presser-head E has on its under side a cavity or recess E, (shown in Figs. 3 and 4,) adapted to receive the. guidebars S S during its descent against the boxblank and box-supports G G.

In practice I prefer to provide the machine with an automatic stopping device for the the treadle after the purpose of stopping the machine after its the crankshaft has performed one complete revolution, so as to cause the head E to be raised to its highest position when the machine is stopped after setting up the box end, and for this purpose I secure to the crank-shaft C a cam 0 having a recessed or reduced portion on its periphery, as shown at c in Figs. 1, 2, and 3. In connection with such cam I use an upwardly-projecting bar or rod Z1 on the treadle B as shown in Figs. 1, 2, and 3.

lVhen the treadle is depressed, the machine is started, as hereinbefore described, and although the operator relieves his pressure on machine has been started said treadle will remain depressed by the cam C acting on the treadle-bar b and the friction-clutch B, coupled to the pulley B, until the crank-shaft C has completed one revolution, when the upper end of the treadlebar b moves into the cam-recess c by the influence of the spring B causing the treadle to be raised, the friction taken off the pulley B, and the machine stopped automatically, leaving the head E in its highest position.

The operation of the machine is as follows: The blanks K are placed in a pile between the walls or guide-plates I I L, and the boxbody K is placed in position on box-support G G, as shown in Fig. 4. Themachineis set in operation by depressing the treadle, causing the feed-plate M to be moved backward sufficiently to expose the lowest blank in the pile, after which the paster-bars or spotters O O R are caused to rise and transfer the paste in spots to the under side of the blank, after which said pasters drop into their normal position in the paste in the box P. The pasted blank is then fed by the plate M, while resting on the springs m m, to the place where it is to be set up or stuck onto the overlapping edges 7.: 7.5 7.: of the box-body. The head E descends and presses the pasted blank onto said edges of the box-body. The head then commences to rise to its highest position, and the operator in the meantime removes the box and reverses it on the boxsnpport for setting up its other end, and so on during the operation of the machine.

T T are laterally-adjustable stops secured in a suitable manner to the front part of the pressure bar or head E, said stops having their lower portions projecting below said head and serve for the purpose of stopping the pasted end blank from being fed too far by the pickenbar and arresting it in its proper position relative to the box-body held upon the box-support.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1.
